Specification of Letters Patent.

Patented July 24, 1906.

Application filed March 1l, 1905. Serial No. 249.661.

To all whom it may concern:

Be it known that I, JOHN HENRY STICHT, of No. 4836 Sherbrooke street, inthe town of Westmount, Province of Quebec, Canada, have invented certainnew and useful Improvenients in Stairways; and I do hereby declare thatthe following is a full, clear, and exact description ofthe same.

My invention relates particularly to the means for connecting the striners of a stairway to the newel-posts; and it as for its 0bject toprovide a connecting device whereby a Stringer can be rigidly connectedto a-newelpost without the use of visible bolts, angles, or otherconnections by manipulating the same from the interior of one end of,preferably, the newel-post.

The invention may be said, briefly, to consist of one or more keyscarried rigidly by one of the parts to be connected and adapted toproject through slots in the other part, the side of such key or keysadjacent to the part upon which it is carried being beveled, a

ocking-bar constructed to present a portion to fit between the beveledside of thekeyor keys and the part through which the latter project, andmeans whereby such lockingar is adjusted-for the the parts together.

For full comprehension, however, of my invention reference mustbe had tothe accompanying drawings, in which similar reference charactersindicate the same parts, and wherein- Fi ure,1 1 is a vertical sectionalview of a newe -post with a stairway-stringer connected theretoaccording `to my invention, the section being taken on line A A, Fi 2.Fig. 2 is a similarjview taken on line B Fig. 1.

The Stringer b and the newel-post c, which is hollow and has a rigidtransverse plate c near its lower end, are of usual construction.

According to my invention the ends of the Stringer (one end onl ofthe'latter is shown) are constructed with preferably a pair of keys d ofT form, having the edges of the flanges thereof adjacent to the Stringerbevpurpose of tightening' eled, as at and slots c2 are formed in theside of the newel-post to allow of the keys d being insertedtherethrough, while a lockingbar e, slotted, as at e', is )fitted overthe keys as they project into the interior of the newelpost, and thelower end thereof is diminished and screw-threaded to project through aperoration in the bottom plate c and receive a nut e2.

In assembling the parts of a stairway according to my invention the keysdare first inserted through the slots c2. The locking-bar e is thenfitted in place and the nut e2 is tightened, thereby wedging theportions of such bar above the slots therein tightly between the beveledsides of the keys and the side through which they project of the` post.

What I claim is as follows:

1. Means rigidly connecting a Stringer and a hollow post together,consisting of a device carried by the stringer and adapted to eX- tendthrough a slot in the post, such device having an inclined bearing-face,,a slidable locking device adapted to be moved into locking engagementwith the said bearingface and means whereby the said locking device ismoved to and from locking engagement with the first-mentioned device. 2.Means rigidly connecting a Stringer to a hollow newel-post consisting ofa key carried by the end of the Stringer and presenting a beveled facetoward the end of the Stringer and adapted to extend through a slot inthe post, a slotted slidable locking-bar presenting a portion engagingbetween the beveled face of the key and the wall of the post throu hwhich the key projects and means where y the said locking-bar isoperated from the end of the newelost.

In testimony whereof have signed my name to this specification in thepresence of two subscribing witnesses.
